CSR8670 在source_usb.c里有一个问题，有谁能告诉我

wgc2013

1. void usb_send_hid_answer(void)
   
2. {
   
3.     if (theSource->ps_config->usb_config.usb_hid_keyboard_interface)
   
4.     {
   
5.         /* send ALT+PGUP over USB */
   
6.        UsbDeviceClassSendEvent(USB_DEVICE_CLASS_EVENT_HID_KEYBOARD_ALT_PGUP);
   
7.     }
   
8. }

复制代码

USB_DEVICE_CLASS_EVENT_HID_KEYBOARD_ALT_PGUP找不到HID相关描述
哪个大神，能告诉我一下，谢谢啦！

楼上，你好！这个表放在哪个文件下的，我没有找到

源代码的source_usb.c里HID描述，里面只有(Consumer Devices)的，哪个大神，能不能给一份里面有(Telephony Devices)的描述？
